IMPROVEMENT IN FLY 0R BALANCE-WHEEL.

tro ALI. WHoM 1T' MAY coNcERN:

Be it known that I, 4ROBBERT RICE, of Mineral, in the county of Bureau, and State ot' illinois, have invented a new and improved Fly or Balance-Wheel; and I do hereby declare that the following is a. full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side view of my invention, the plate or side of the wheel nearest the eye being removed in order to show the interior.

Figure 2, e section ofthe sam-e taken in the line x z, fig. 1.

Similar letters of reference indicate correspondingtparts.

This invention consists in constructingr a fiy or balance-wheel, with a .series of internalvchambers, arranged in such a manner that by partially filling said chambers with water or other suitable fluid the gravity of the latter willbe rendered subservient as en assistant motor or an economizer of power.

A represents a Hy or balance-wheel, which is hollow, and provided with partitions a, which divide the wheel into a series of compartments, B, of peculiar form, as shown cleurly in iig. 1, the partitions a extending from the hub bof the wheel to its rim c, in a sinuous manner. In each compartment B there is a fixed plate, d. These plates are placed longitudinally in the compartments, a space or opening being allowed nt each end, as shown in iig. 1.

This I'iy or balance-Wheel is placed or keyed on a shaft, as usual, and the compartments B are partially supplied with wet-er, (about halfl tilled,) and it will be seen by referring to tig. 1 that. the water in the right-hand compartments B will have their water in the lower parts of the sume, und near the periphery ofthe wheel, while those nt the left-hand side have their water near the shaft. This result is owing to the peculiar shape or form of the compartments B, and it will further be seen that owing to the water assuming the position in the com; partments as specified, the wheel will exert an influence as n motor when rotating in the direction indicated by arrow 1.5 The plates d serve as breaks or guards to prevent the water boing thrown outward in the left-hand compartments under centrifugal force.

Having thus described my invention, what I claim as new, and desire to secure by LettersPatent, is-

A ily er balance-wheel, provided internally with compartments, oi` the form substantially as shown, and partially filled with water or other suitable'fuid, to operate in the manner and for the purpose set forth.
